Sažetak
Landfill leachate is defined as the aqueous effluent generated as a consequence of rainwater percolation through wastes, biochemical processes in waste's cells and the inherent water content of wastes themselves. Biological treatments are often used for the removal of the bulk of leachate with high chemical oxygen demand (COD) values primarily due to their higher reliability, simplicity and cost effectiveness of these processes. The aim of this work was to study the efficiency of biodegradation of organic pollutants in laboratory prepared leachate from tobacco dust waste under batch conditions. Further, the purpose of this work was also to mathematically describe the process in order to enable better understanding of biodegradation of organic matters in leachate. Toxicity test with Vibrio fischeri, pH value, dissolved oxygen (DO), COD, mixed liquor suspended solids (MLSS) and mixed liquor volatile suspended solids (MLVSS) have been monitored during the experiments. The microscopic analysis was conducted to study the development of activated sludge flocs and its morphology. Leachate samples were found to be biodegradable and more than 72 % COD was removed.
